PATENT OFFICE.

O THE WESTERN GALVANIC BATTERY.

SPECIFICATION forming part of Letters Patent No. 423,594, dated March 18, 1890. Application filed December 9, 1889. $erial No. 333,134. (No model.)

To all whom, it may concern:

Be it known that I, MARTIN M. 'CLARK,-a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Leclanch Batteries, (Case 6,) of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming apart of-this specification.

My invention relates to Leclanch batteries, and its object is to provide for supporting the porous cup and zinc in proper position within the jar.

My invention consists in a ring or collar, preferably of wood, which is placed upon the top of the jar, in combination with rubber bands or stops, one placed above and one below the same about the upper portion of the porous cup, together with the porous cup and zinc. Instead of the upper rubber band, a shoulder may be provided upon the porous cup, as hereinafter described.

My invention will be readily understood by reference to the accompanyings drawings, in

which-'- Figure 1 is an elevation of a cell of Leclanch battery embodying my invention, the collar and rubber bands being shown partially broken away. Fig. 2 is a top or plan View of the same. Fig. 3 is a view showing the shoulder upon the porous cup in place of the upper rubber band.

Like parts are indicated by similar letters of reference throughout the different figures.

The glass jar a may be of the usual form and adapted to hold the sal-ammoniac solu- The porous cup I) is likewise of usual construction, and is preferably sealed at the top about the carbon plate in the usual manner. The ring 0 is preferably of wood and rests upon the upper edge of the glass jar, as shown. Rubber rings d and e, placed about the jar, as shown-one above and one below the A collar-serve as adjustable stops. Thus the jar may be adjusted to any desired height. The zinc rod f, inserted through a hole provided in the collar, as shown, anda rubber band g upon the same, serving as a stop, permits the rod tobe adjusted to any height desired, preferably so that its lower end shall be in the same horizontal plane with the bottom of the jar, or thereabout.

As shown in Fig. 3, a shoulder h is provided upon the upper edge of the porous cup to take the place of the upper rubber band 6. (Shown in Figs. 1 and 2.)) 7

My invention as thus described provides a stop above and below the supporting-collar. 7

These stops not only perform the function of supporting the cup, but also prevent the salts from creeping over the top of the cup. I

have described a shoulder formed on the cup claim as new, and desire to secure by Letters Patent 1. The combination, with the jar, of the collar c, placed upon the upper edge thereof, the porous cup inserted through said collar, and the adjustable rubber-bands, one above and one below the'collar, serving as stops, and the zinc rod, also supported upon the collar bya rubber band, serving as an adjustable stop, substantially as and for the purpose specified.

2. The combination, with the porous cup suspended in the jar by a wooden collar resting upon the upper edge thereof, of an adj ustable stop in the form of a rubber band surrounding said porous cup below the ring and a stop upon said cup above the ring, substantially as and for the purpose specified.

In witness whereof I hereunto subscribe my name this 14th day of March, A. D. 1889. MARTIN M. CLARK.- Witnesses:
